Lunar year series

Lunar Saros 133

This lunar eclipse is part of series 133 of the Saros cycle, which repeats every 18 years and 11 days. Series 133 runs from the year 1557 until 2819. The previous eclipse of this series occurred on January 30, 1972 and the next will occur on February 21, 2008.

It is the 5th of 21 total lunar eclipses in series 133. The first was on December 28, 1917. The last (21st) will be on August 3, 2278. The longest two occurrences of this series (14th and 15th) will last for a total of 1 hour and 42 minutes on May 18, 2152 and May 30, 2170. Solar saros 140 interleaves with this lunar saros with an event occurring every 9 years 5 days alternating between each saros series.

Half-Saros cycle

A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).[2] This lunar eclipse is related to two annular solar eclipses of Solar Saros 140.
